2.3. Ringing mode
In ringing mode (Ring relay in position 2), the only protection device involved is the CLP270M.
In normal conditions, the CLP270M operates in region 1 of
A1
curve, and is idle.
If an overvoltage occuring between TIP (or RING) and GND reaches the internal overvoltage reference
(+/- 270 V), the CLP270M acts and the line is short-circuited to GND. At this time the operating point
moves to region 2 for positive surges (region 3 for negative surges). Once the surge current falls below
the switch off current I
SWOFF
, the device returns to its initial state (region 1).
For surges occuring between TIP and RING, the CLP270M acts in the same way. This means that the
CLP270M ensures a tripolar protection.
Whenusedalone,theCLP270Mactsattheinternalovervoltagereferencelevel(+/-270V).Furthermore,it
is possible to adjust this threshold level to a lower voltage by using:
